As described above, in digital image interpretation, the display is very important as the final imaging device, because the quality of the display effect has a crucial influence on the final diagnosis result. And with the improvement of the technology and the enhancement of health consciousness of people, the daily workload of doctors is extremely large, and on average, 150 tablets per day need to be diagnosed by each doctor, so that how to improve the working efficiency of the doctors and the comfort and accuracy in the using process become important.

However, the inventor has found that in the medical display in the prior art, the brightness of the display is adjusted by the key. But it is possible that the doctor is not familiar with the operation of the display keys, resulting in a constant brightness during use. For example, the default brightness for power-on is 400cd (candela)/m²The backlight brightness will be constant at 400cd/m during the use period of the doctor²However, the luminance is not applicable to all images, e.g., some images may have a preferred viewing luminance of 500cd/m²At this luminance the image contrast is optimal and the sharpness is better, if at 400cd/m²The brightness of the light source can lead to insufficient contrast, and the detailed information of the focus can be difficult or even impossible to observe. Moreover, if the brightness of the display is required to be adjusted, the brightness is required to be adjusted by the brightness key all the time, but it is very inconvenient to switch the brightness by the key all the time in use, which results in low efficiency of browsing medical images.

In view of this, the present application provides a medical image display method, which can automatically adapt to a better display brightness according to the characteristics of a medical image without manually adjusting the brightness. So that the details of the medical image can be clearly displayed for the medical staff to observe. Therefore, the method provided by the application can adaptively adjust better display brightness so as to accurately and clearly display details of the medical image, and can improve the comfort level and contrast of the medical image viewed by medical staff, thereby providing support for ensuring the accuracy of the medical image-based film reading diagnosis.

Therefore, the application provides a medical image display method and a communication terminal. The present application will be described in detail below with reference to the accompanying drawings.

Before proceeding with a detailed analysis of the present application, it is noted that: the format of display of medical images in this application may be Digital Imaging and Communications in Medicine (DICOM) format, which is an international standard for medical images and related information. DICOM is widely used in radiology, cardiovascular imaging, and radiodiagnostic devices. All medical images of patients are stored in the DICOM file format, which may contain information about the patient, such as name, sex, age, and other image-related information such as device information for capturing and generating the images, some contextual information for medical treatment, etc. The medical imaging apparatus generates a DICOM file, and a doctor reads and diagnoses a problem found in an image using a DICOM reader (computer software capable of displaying a DICOM image).

The currently adopted standard is DICOM3.0, each medical image carries a large amount of information, and the information can be specifically classified into the following four types:

(a) patient, includes all basic information (e.g., name, sex, age, etc.) of the Patient and physician-specified exam student.

(b) The assigned exam studio contains the exam type (e.g., computed tomography CT, magnetic resonance exam MR, ultrasonography, etc.) and the sequence Series of the assigned exam.

(c) The sequence Series of examinations contains the technical conditions of the examination (for example milliamp, field angle FOV, layer thickness, etc.) and the IMAGE.

(d) The medical Image.

The sequence of inspection may include the contents as shown in table 1: the examination sequence of the CT images is shown in fig. 2. In fig. 2, Group represents a tag Group, Element represents an Element Value, Title represents a tag description, and Value represents a specific Value.

Table 1;

as shown in fig. 3, fig. 3 is a scene schematic diagram of the medical image display method of the present application. The scene is schematically illustrated by a memory 310, a server 320 and a terminal 330. The memory 320 stores medical images, the terminal 330 is installed with image browsing software 340 and upper computer software 350, the user a obtains the medical images corresponding to the patient from the memory through the image browsing software 340 on the terminal 330 and sends the medical images to the server 320, and after receiving the medical images, the server 320 obtains feature information of the medical images and identifies the backlight unit in the display area of the medical images. Then, the server 320 determines the brightness of the backlight unit in the display area of the medical image from the corresponding relationship between the feature information and the brightness stored in the upper computer software 350, and sends the brightness to the upper computer software 350, and the upper computer software 350 adjusts the brightness of the backlight unit in the display area of the medical image of the terminal to the determined brightness.

Referring to fig. 4, fig. 4 is a flowchart illustrating a medical image displaying method according to the present application, which may include the following steps:

step 401: acquiring characteristic information of the medical image; and after displaying the medical image, identifying a backlight unit within a display area of the medical image; the feature information comprises a category of the medical image and/or an image value distribution feature of the medical image;

step 402: and adjusting the brightness of the backlight unit in the display area to the brightness corresponding to the characteristic information of the medical image.

And storing the brightness corresponding to the characteristic information of the medical image in the corresponding relation between the characteristic information and the brightness, wherein the corresponding relation supports user self-definition.

For example, as shown in fig. 5, fig. 5 includes a terminal computer 510, a medical professional display 520, and an image browsing software 530 installed in the computer 510 for displaying medical images and a host computer software 540 for controlling relevant parameters of the medical professional display 520. The image browsing software 530 is used for displaying medical images in DICOM format. The image browsing software 530 corresponds to a microsoft photo viewer, and can open a picture in a compressed format jpg \ image file bmp or the like, and is capable of analyzing a medical image conforming to the DICOM protocol. The original medical image (DICOM) file is large, for example, the file generated by nuclear magnetic resonance easily reaches hundreds of millions, so the medical image can only be checked through professional software, and information loss cannot be caused.

The user opens the file data of the medical image and the image browsing software 530 displays the medical image. When the user selects the medical image, the display frame of the medical image is a red frame. The image browsing software 530 sends the medical image to the computer 510, and after the computer 510 receives the medical image, the computer 510 obtains feature information of the medical image, where the feature information includes a category of the medical image and an image value distribution feature of the medical image, and identifies a backlight unit in a display area of the medical image. Then, the computer 510 determines the brightness of the backlight unit in the display area of the medical image from the corresponding relationship between the feature information and the brightness stored in the upper computer software 540, and sends the brightness to the upper computer software 540, and the upper computer software 540 adjusts the brightness of the backlight partition in the display area of the medical image in the medical dedicated display 520 according to the brightness. The correspondence between the feature information and the brightness stored in the upper computer software 540 can be shown in table 2, where it should be noted that the brightness in the table represents the better observed brightness of the image corresponding to the feature information, and the brightness is preset according to the research. And meanwhile, the brightness is set in a user-defined form.

Table 2;

as described in the background, in the medical display of the prior art, the brightness of the display is adjusted by the keysHowever, the doctor is not familiar with the operation of the display keys, which results in constant brightness during use, e.g. 400cd/m brightness default to power-on²The backlight brightness will be constant at 400cd/m during the use period of the doctor²Since the preferred viewing brightness of CT type images is 400cd/m²Therefore, when a CT type image is observed, the display effect observed under the brightness is better. However, when the molybdenum target type image is observed, the preferable observation luminance is 500cd/m because of the molybdenum target type image²Therefore, the effect of observing the molybdenum target type image at this brightness is relatively poor. Or, the preferred observed brightness of the corresponding image when the image value feature distribution is CT feature is 400cd/m²Therefore, when the image of the CT characteristic is observed, the display effect observed under the brightness is better. However, when the image value characteristic distribution is observed as an image of the molybdenum target characteristic, the preferred observation luminance of the image in which the image value characteristic distribution is the molybdenum target characteristic is 600cd/m²Therefore, the effect of the image value characteristic distribution of the luminance being the image characteristic of the molybdenum target is relatively poor. And when the brightness of the display is to be adjusted, it is necessary to always adjust the brightness by the brightness button, for example, the preferred observation brightness of CT type image is 400cd/m²When CT type images are browsed, the brightness needs to be adjusted to 400cd/m by pressing a key²If the molybdenum target image needs to be browsed, the brightness needs to be adjusted to 600cd/m through the key²Therefore, the doctor needs to adjust the brightness by pressing the keys all the time, which results in low work efficiency. Moreover, many times, only an attempt is made to adjust the brightness of the display, and the brightness adjustment of each medical image is only suitable for experienced doctors, and it is not possible to specifically quantify what range of brightness each medical image is suitable.

For convenience of understanding, the following description will be made on how to determine feature information of a medical image, a display area of the medical image, and the like, respectively:

1. characteristic information of the medical image:

according to the above scheme of the present application, the features of the medical image are first obtained, and the feature information in the present application includes two, which are the category of the medical image and the image value feature distribution of the medical image.

And when the acquired characteristic information is the type of the medical image, acquiring the image type of the medical image and identifying a backlight unit in a display area of the medical image. For example, if the medical image is in CT type, the brightness of the backlight unit in the display region of the medical image is adjusted to the preferred viewing brightness of CT type of 400cd/m²If the medical image is of molybdenum target type, adjusting the brightness of the backlight unit in the display area of the medical image to be the preferred observation brightness of the molybdenum target type of 500cd/m²。

When the acquired feature information is the image value distribution feature of the medical image, according to the relationship in the table 2, if the image value distribution feature is the CT feature, the brightness adjusted by the backlight unit in the display area of the medical image is adjusted to the better observation brightness 400cd/m corresponding to the CT feature²If the image value distribution characteristic is the molybdenum target characteristic, adjusting the backlight unit in the display area of the medical image to the better observation brightness 500cd/m corresponding to the molybdenum target characteristic²。

Therefore, the backlight unit in the display area of the medical image is automatically adjusted to be the better observation brightness through the characteristic information of the medical image, so that the content of the medical image can be clearly and accurately displayed, and the medical staff can observe the medical image conveniently. And the comfort level and the contrast of the viewed image are improved, so that support is provided for guaranteeing the accuracy of diagnosis based on the medical image.

The feature information includes a category of the medical image and/or an image value distribution feature of the medical image.

(2) Acquiring the image value distribution characteristics of the medical image:

the method can be implemented by counting a gray scale distribution histogram of the medical image and determining the ratio of the number of pixels in each designated gray scale value range to the total number of pixels of the medical image according to the distribution histogram; and then selecting the designated gray value range with the highest ratio as the image value distribution characteristic of the medical image.

For example, each designated gray scale value range includes a gray scale value less than 50, a gray scale value within a range of 50-100, a gray scale value within a range of 100-180, and a gray scale value above 180. For example, the ratio of the pixel data in each designated gray scale value range to the total data in the total backlight unit of the medical image is determined as follows: for example, the pixel data with the gray value below 50 accounts for 10% of the total number of pixels in the total backlight unit of the medical image; pixel data with gray value within 50-100, wherein the total pixel data in the total backlight unit of the medical image accounts for 30%; the pixel data with the gray value of 100-180 accounts for 20% of the total number of pixels in the total backlight unit of the medical image; the proportion of the total number of pixels of the pixel data with the gray value above 180 in the total backlight unit in the medical image is 40%. Determining that the gray value with the highest ratio is more than 180 as the image value distribution characteristic of the medical image. It should be noted that, the ratio of each designated gray scale value range and the ratio of the number of pixels in each designated gray scale value range to the total number of pixels of the medical image in the embodiment of the present application are only used for illustrating the embodiment of the present application, and are not limited to the embodiment of the present application.

Therefore, the type of the medical image and the image value distribution characteristic of the medical image can be respectively determined through the two modes.

2. Regarding identifying the display area of the medical image:

in one implementation, the display area of the medical image may be determined in two ways:

the first method is as follows: sequentially identifying each pixel row and each pixel column in the medical image according to a specified sequence; for any pixel row, if the difference value of the pixel values of all the pixels in the pixel row is within a specified range, determining the pixel row as the transverse boundary of the display area of the medical image; for any pixel column, if the difference value of the pixel values of all the pixels in the pixel column is within a specified range, determining the pixel column as the longitudinal boundary of the display area of the medical image; determining a region composed of the lateral boundary and the longitudinal boundary as a display region of the medical image.

For example, as shown in fig. 6, the image browsing software divides the display area of the medical image by pixel lines, for example, sequentially identifies the pixel rows from top to bottom, and sequentially identifies the pixel columns from left to right, and if the difference between the pixel values of the pixels in the pixel rows x1 and x2 is within a specified range, the pixel rows x1 and x2 are determined as the lateral boundaries of the display area of the medical image. If the difference between the pixel values of the pixels in the pixel rows y1 and y2 is within a predetermined range, the pixel rows y1 and y2 are determined as the vertical boundaries of the display region of the medical image, and the region composed of the horizontal boundaries x1 and x2 and the vertical boundaries y1 and y2 is determined as the display region of the medical image.

The second method comprises the following steps: acquiring display description information, wherein image identifiers of medical images displayed in each display area are defined in the display description information; and inquiring a display area identifier corresponding to the image identifier of the medical image from the display description information to obtain a display area of the medical image.

For example, as shown in fig. 7B, display description information is acquired, in which the image identifier of the medical image displayed in each display region is defined, and for example, in fig. 7B, the identifiers of the display regions are respectively display region 1, display region 2, display region 3, and display region 4 in the order of zigzag. The images of the medical images displayed in the respective display areas are denoted as image 1, image 2, image 3, and image 4. If the display area of the image 1 needs to be acquired, inquiring a display area identifier corresponding to the image 1 from the display description information, and if the determined display area identifier is the display area 1, determining the display area corresponding to the display area 1 as the display area of the image 1.

Thus, the display area of the medical image can be determined in the two ways.

In one embodiment, the adjusting the brightness of the backlight unit in the display area to the brightness corresponding to the feature information of the medical image in step 402 may be implemented as shown in fig. 7A-7B, for any backlight unit in the display area:

if all the pixel points in the display range corresponding to the backlight unit belong to the medical image, adjusting the brightness of the backlight unit to the brightness corresponding to the characteristic information of the medical image;

wherein the specified conditions include any one or combination of:

(1) the medical image is located at the designated position of the other medical images;

for example, if the designated orientation is the left orientation, the brightness of the backlight unit 20 is adjusted to the brightness corresponding to the feature information of the medical image 1 if the medical image 1 is located at the left orientation of the medical image 2.

(2) Receiving a selection instruction for the medical image.

For example, the user selects the brightness of the backlight unit 20 to be consistent with the brightness corresponding to the feature information of the medical image 1, and if the brightness corresponding to the feature information of the medical image 1 is a, the brightness of the backlight unit 20 is adjusted to be a.

For example, as shown in fig. 7A, the black dashed cell in the figure represents a backlight unit, and the exemplary backlight unit in the figure is a 10 × 10 backlight unit, wherein 4 red cells in the figure represent display areas of medical images, and sequentially in a zigzag order: as shown in fig. 7B, the medical image corresponding to the display area 1 is a medical image 1, the medical image corresponding to the display area 2 is a medical image 2, the medical image corresponding to the display area 3 is a medical image 3, and the medical image corresponding to the display area 4 is a medical image 4. The above-described aspects of the present application are described in detail with respect to the display area 1: for any backlight unit in the display area, if each pixel point in the display range corresponding to the backlight unit belongs to the medical image 1 in the display area 1, for example, each pixel point in the display range corresponding to the backlight unit 1-the backlight unit 19 belongs to the medical image 1. The brightness of the backlight unit 1-the backlight unit 19 is adjusted to the brightness corresponding to the characteristic information of the medical image 1.

The pixel points in the display range corresponding to the backlight unit 20 are divided into two parts, wherein 1 part belongs to the medical image 1, and the other part belongs to the medical image 2 in the display area 2, and when the medical image meets the specified condition, the brightness of the backlight unit 20 is adjusted to the brightness corresponding to the feature information of the medical image 1.

Therefore, the brightness of the backlight unit can be adjusted according to the corresponding mode by firstly identifying whether the pixel points in the backlight unit belong to the same medical image or one part of the pixel points belong to the medical image and the other part of the pixel points belong to other medical images.

In one embodiment, if the medical image does not satisfy the specified condition, the brightness of the backlight unit is adjusted to the brightness corresponding to the feature information of the other medical images satisfying the specified condition. For example, if the medical image 3 in the display area 3 satisfies the predetermined condition, it is determined that the brightness corresponding to the feature information of the medical image 3 is brightness B, and the brightness of the backlight unit 20 is adjusted to brightness B.

Therefore, the brightness of the backlight unit can be determined according to the brightness corresponding to the characteristic information of the medical image meeting the specified condition.

step 801: acquiring header file information of the medical image;

step 802: analyzing the category parameters of the header file information to obtain the category of the medical image;

step 804: aiming at any backlight unit in the display area, judging whether each pixel point in a display range corresponding to the backlight unit belongs to the medical image or not; if yes, go to step 805, otherwise go to step 806.

Step 805: adjusting the brightness of the backlight unit to a brightness corresponding to the feature information of the medical image;

step 806: if the pixel points in the display range corresponding to the backlight unit are divided into two parts, wherein one part belongs to the medical image, and the other part belongs to other medical images; judging whether the medical image meets specified conditions or not; if yes, go to step 807, and if no, go to step 808.

Wherein the specified conditions include any one or combination of: the medical image is located at the designated position of the other medical images; receiving a selection instruction for the medical image;

step 807: adjusting the brightness of the backlight unit to a brightness corresponding to the feature information of the medical image;
